The K2 (Korean더 케이투; RRDeo Keitu) is a 2016 South Korean television series starring Ji Chang-wook, Song Yoon-ah and Im Yoon-ah. It premiered on tvN every Friday and Saturday at 20:00 (KST) from September 23 to November 12, 2016 for 16 episodes.[1]


Kim Je-ha is a former mercenary soldier for the PMC Blackstone. While in Iraq, Je-ha gets framed for the murder of his lover Raniya, a civilian, and becomes a fugitive. Je-ha escapes and returns to South Korea, where he is offered work as a bodyguard by Choi Yoo-jin, the owner of JSS Security Company and wife of presidential candidate Jang Se-joon. Je-ha accepts the job in exchange for resources that he needs to exact revenge on another presidential candidate Park Kwan-soo, who previously ordered Raniya's killing.

Je-ha is assigned to guard Go An-na, Jang Se-joon's secret daughter, as An-na's life is always threatened because of her stepmother Yoo-jin. An-na, who has been a recluse and lonely all her life, starts relying on Je-ha, who shows concern for her and protects her everytime. They slowly fall in love, causing Je-ha to be torn between having to work with his boss Yoo-jin to exact revenge on Park Kwan-soo and protecting An-na against the wishes of Yoo-jin.

Another key figure is Choi Sung-won, Choi Yoo-jin's half brother and the son of her father's mistress and eventual second wife, who is his half-sister's fierce rival. Plotting with Park Kwan-soo, Sung-won eventually causes the deaths of Jang Se-joon and Choi Yoo-jin but later pays for this with his life at the hands of Choi Yoo-jin's devoted assistant Kim Dong-mi. Park hangs himself for his atrocious acts and Je-ha finally proves his innocence and achieves his goal of revenge. Je-ha and An-na leave for a foreign country and embrace each other. An-na asks Je-ha about his real name and Je-ha reveals his name.



The main protagonist of the series. He is a former Blackstone military operative who had been stationed in Iraq until he flees South Korea after being framed for murder. His skills come to the attention of Choi Yoo-jin, who hires him to work for her security agency JSS Security under the codename K2, and is assigned as bodyguard to Go An-na, the secret illegitimate daughter of Choi's husband, Jang Se-joon. The name "Kim Je-ha" is not Je-ha's real name but an alias he uses to conceal his identity while working as An-na's bodyguard; the name actually belongs to a victim of an unsolved missing person case. The real name of the protagonist is unknown throughout the show, except that his real surname is said to be Kim.
She is the wife of Jang Se-joon. The eldest daughter of a chaebol family, she was disinherited from the JB Group conglomerate as her father disapproved of a politician as a son-in-law, although she received control of JSS Security. Ambitious and merciless, her corrupt nature is due to the result of her upbringing. She sets her sights on becoming the First Lady and is willing to manipulate An-na and her husband to further her aims. As the series progresses, she begins to develop feelings for Je-ha after he rescues her from an exploding car.

After her father's affair was discovered, An-na was exiled from Korea and grew up in Spain at a convent, under the constant surveillance of her cruel stepmother Choi Yoo-jin. An-na has developed a social phobia and experiences panic attacks from flashing lights, a result of PTSD stemming from her past connection to the death of her biological mother. She returns to South Korea from Barcelona and becomes a pawn in her stepmother's plan to control her husband's political career from behind-the-scenes. She later falls in love with Je-ha.
He is a philandering presidential candidate partially responsible for corrupting his wife. He is also An-na's biological father. Because of An-na, whose existence is unknown to the public, he is unwillingly under the control of his corrupt wife, who blackmails him into doing her bidding. Throughout the series, he doesn't seem to show that he cares for his daughter, but later he reveals to Je-ha that he truly loves her and is willing to submit to his wife just to keep An-na safe.
He is Se-joon's political rival and leader of the current ruling party. He is the main antagonist of the series.


Yoo-jin's younger half-brother and the current CEO of the chaebol JB Group. Both he and his sister are at odds for the majority control of both JSS Security and their family company.

The drama is written by scriptwriter Jang Hyuk-rin, who wrote Yong-pal (2015) and directed by Kwak Jung-hwan of Neighborhood Hero (2016).[12][13]

Being depicted with a bodyguard action theme, the drama utilized various fighting techniques including systema, taekwondo, aikido, and jujutsu for its action scenes. It became the first Korean television drama to introduce the Bullet Time effect.[14][15]

The first script reading was held in August 2016 at the CJ E&M Center in Seoul, South Korea.[16] Filming began in September.

Some scenes of the drama, primarily in episodes 1 and 2, were filmed in Catalonia (along the mountain of Montserrat, the Gothic and Baroque Cistercian Monastery of Santes Creus in Aiguamúrcia), followed by various places in Barcelona (center, Old City, etc., as well as various metro / commuter rail stations such as Plaça d'Espanya and Magòria / La Campana), Gaudí's Modernista Colònia Güell Crypt (fashion show party) among other locations in Spain (probably near Almería for the Iraq War desert locations). The closing scene of episode 16 was filmed at Barcelona's Turó de la Rovira hill.[17][18][19][20][21] The rest of the series was apparently filmed in Korea.

The male lead Ji Chang-wook, due to his casting, became the highest-paid actor for a tvN drama.[20] He had special training and performed the action stunts in the drama by himself, without a body double.[21] At the press conference, director Kwak expressed "On top of Ji's splendid action, the drama will tell the story of insatiable desire and political fights between people holding secrets of their own."[15]
